泌尿系感染是小儿时期常见的感染性疾病,其复发和再感染多伴有泌尿系统结构异常。超声检查诊断急性肾盂肾炎有重要价值。腹部X线平片是检查结石的首选方法。排泄性泌尿系超声检查是诊断膀胱输尿管反流的前沿方法。排泄性膀胱尿道造影可确诊膀胱结石。计算机体层成像和磁共振成像能准确检测儿童泌尿系感染肾损害,但因其昂贵及需使用造影剂,目前不列为常规应用。二巯基琥珀酸扫描是评估肾瘢痕的标准检查方法。直接法放射性核素膀胱显像检测膀胱输尿管反流敏感度高。
Urinary tract infection is a common infectious disease in infancy, the recurrence and re-infection often accompanied by urinary system structural abnormalities. Ultrasound diagnosis of acute pyelonephritis has important value. Abdominal X-ray is the preferred method of checking for stones. Excretory urinary ultrasound is the diagnosis of bladder ureter reflux front. Bladder urethral catheterization can be diagnosed with bladder stones. Computer tomography and magnetic resonance imaging can accurately detect urinary tract infection in children with renal damage, but because of its expensive and need to use contrast agents, is currently not listed as a routine application. Dimercaptosuccinate scan is a standard test for evaluating renal scarring. Direct method of radionuclide cystography in detecting vesicoureteral reflux sensitivity.
